Question

What boiling point of solid if we go from sea level to high?

Answer 1

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude

Answer 2

boiling point increases with increase in altitude due to decreasing pressure and temperature

p.s. solids don't boil, they melt :)
